What Are the Product Testing Standards of GRC Manufacturers? An Analysis of the GRC Testing Standard System

Testing of GRC products must follow national industry standards and enterprise standards. The standard currently mainly implemented is "Glass Fibre Reinforced Cement Decorative Products" JC/T 940, which specifies the technical requirements, test methods, and inspection rules for GRC products.

In terms of implementing testing standards, Qinglong GRC has established a comprehensive enterprise standard system, with many indicators stricter than national standard requirements. For example, the national standard requires flexural strength ≥15MPa, while Qinglong's enterprise standard raises it to ≥18MPa; the national standard specifies water absorption ≤12%, while Qinglong controls it at no more than 10%. Such strict standard requirements ensure that product performance exceeds the industry level.

National Standard Requirements

JC/T 940 is the basic standard, specifying technical requirements. GB/T 17671 is the test method standard. These standards are the fundamental basis.

Enterprise Standard System

Quality manufacturers formulate enterprise standards stricter than national standards. Enterprise standards must be filed and registered. These standards reflect the pursuit of quality.

Testing Item Setup

Mechanical performance testing is the foundation. Durability testing predicts service life. Appearance quality testing ensures aesthetics. These tests comprehensively assess quality.

Testing Method Specifications

Standard testing methods are strictly implemented. Calibrated and qualified equipment is used. Testing personnel are certified for their posts. These specifications ensure data accuracy.

Testing standards are the foundation of quality assurance. Choosing manufacturers that implement strict standards provides better assurance of product quality. Qinglong GRC strictly implements standards to ensure product quality.
